PERM'UTATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 330,137,dated November10, 1885.

Application filed May 25, 1885.

To all whom it mag concern.-

Be it known that I, WALTER E. MALLEY,

of New Haven, in thecounty of New Haven.

and State of Connecticut, have invented a new and Improved Combinationand Permutation Lock, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improved combinationand permutation lock which is simple in construction, safe and reliable,and not apt to get out of order.

The invention consists in the combination,

with a casing,a sliding bolt, and a sliding tum bler,ofratchet-wheelsadapted to engage with the tumbler, and of push-pins or other devicesfor turning the ratchet-wheels to permit the tumbler to slide,the saidratchet-wheels beingv secured to the same and to the ratchet-wheels"Each ratchet-wheel is providedwith a laterally-projecting pin adaptedto engage with a pin or projection on the casing.

The invention also consists in parts and details and combinations of thesame, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a cross-sectional elevation of my improved lock on the linea: m, Fig. 2. Fig. 2 is a longitudinal sectional view on the line y y,Fig. 1. Fig. 3 is a plan view of the bolt. Fig. 4 is a perspective viewshowing the ar rangement of the push-pins. Fig. 5 is a face view of oneof the ratchet-wheels. I

In the casing A a sliding bolt, B, is held, the beveled end of this boltbeing projected from the end of the casing by a spring, B, in the usualmanner, and the said bolt being pro vided at its forked inner end withteeth or projections 13*, on which the arms G (J of a nut, 0 on theknob-shaft O are adapted to act for the purpose of withdrawing the bolt.A

sliding tumbler, D, is provided at the ends with notches or recesses D,which engage the Serial No. 166,589. ,(ModeL) tongues or cross-pieces E,secured to or cast upon the casing, and adapted to guide thesaidtumbler. The tumbler is also provided in its upper edge with a notch orrecess, D into which the end of the downwardly-projecting arm 0 of thenut (3 passes. The tumbler is drawn in the inverse direction of thearrow a a, is held, the said pins being adapted to strike correspondingpins, I, projecting from the inner surface of the casing. Adjacent toeach ratchet-wheel a fiat spiral spring, J,

is coiled around the shaft, and has one end secured to the said shaftand the other end to the side ofthe ratchet-wheel, the said springsswinging the wheels in the direction of the arrow 1), Fig. 1. Againstthe toothed edge of each ratchet-wheel a locking-spring,

. K, rests, which is secured to the casing at or near the bottom. Fromthe side of the casing a rectangular orother neck, L, projects, which isprovided with an extension-piece, L, fitting in the said neck, the saidextension-piece being provided with an escutcheon-plate, M, to fit onthe outer surface of the door, in which the lock is mortised. Thisextension-piece has to be provided, as the thicknesses of doors vary. Insome cases the escutcheon-plate M is on the outer edge of the neck L,and in some cases it is a greater or less distance from the same.

The neck L can be held in the casing in any suitable manner, but Iprefer to form eyes s on the edges of the opening, and correspond ingeyes on the inner edges of the neck, the eyes of the neck and openinginterlocking, and then I pass a screw, t, through the said eyes from theend of the lock-casing, thus holding the neck on the casing.

In the plate M three pins, N N 2 N, are held of each pin a pawl, O, ispivoted, which is held raised by a spring, P. The pawls are so arranged,that they can act upon the corresponding ratchet-wheels, H, H and HSpiral springs Q surround the'push-pins N N N and push them outward.Below the above-mentioned push-pins a push-pin, R, is arranged in theplate M, which is also pressed outward by a spring, Q, and has across-piece, It, on its inner end, the said cross-piece extending acrossto the spiings K, as shown in Fig. 4. To the inner end of the push-pin Nan elbow, n, is secured, and projects downward, and to the elbow acrosspiece, n, is secured, which is provided at each end with a tooth,M, the said teeth a being adapted to act on the springs K of theratchet-wheels H andH On the push-pin N adownwardlyprojecting elbow, m,is secured, and to the same a cross-piece, m, is fastened, which isprovided on its free end with a tooth, m

adapted to act onthe spring K of the ratchetwheel H The cross-pieces orrods n m constitute the permutation devices, and may be left off or maybe applied, as desired.

' In the bottom of the sliding tumbler D two notches, S, are formed,which correspond in position to the ratchet-wheels H and H, the end ofthe tumbler being adjusted to the third ratchet-Wheel, and in that edgeof each notch- S facing the ratchet-Wheel.

The operation is as follows: To unlock the lock, the notches H of thethree wheels H H 11 must be inline, so that the tumbler can be passedinto the said notches. In order to bring the notches in this position,the wheels are revolved the distance of one, two, or more teeth by meansof the push-pins N N 2 N By pushing the said pins in their pawls engagewith the teeth of the ratchet-wheels and revolve the ratchet-wheels. Forexample, the wheel H is to be revolved the distance of one tooth,theiwheel H the distance of two teeth, and the wheel H the distance ofthree teeth. For this purpose the lock mnst' first be ad-. j usted,which is accomplished by placing the removable pins a in the aperturesof difierent teeth. The pin a in the disk H is placed one tooth from thenotch, in the disk H it is placed two teeth from the notch, and in thedisk H it is placed three teeth from the notch, the said pins resting onthe corresponding pins, I, as the wheels are thrown in the direction ofthe arrow 1) until they rest on the said pins I. If the disks orratchet-wheels have been so adjusted that the notches are in line, theknob is turned and the bolt withdrawn, and at the same time the tumblerD is moved in the direction of the arrow a and through the notches ofthe ratchet-wheels. is released, the spring B pushes the bolt outward,and the spring F pulls the sliding tumblers in the inverse direction ofthe arrow a. The pin R is pressed inward to throw oft the springs K, orone or more of the push-pins N N N are pushed inward one or more times,so as to shift the ratchet-wheels in such a manher that the notches willnot be in line, thus making it impossible to shift the tumbler.

wise the notches will not come in line.

When the knob-shaft If at any time the bolt is to be withdrawn, thepush-pin R is pushed inward so as to disengage the springs K from theratchet-wheels, thus permitting the several springs J to swing the threeratchet-wheels in the direction of the arrow 22 until they rest on theirpins I. The several ratchet wheels are thus thrown into their normalposition, and if they are By adjusting the pins a in holes in differentteeth various combinations can be produced.

For instance, one wheel can be set to be re volved one tooth, anothereight, and the other six, and so on. It is evident that a greater numberof ratchet' 'wheels and corresponding push-pins can be used. Theratchet-wheels turn in the notches S of the sliding tumbler.

,When the purmutation device shownin Fig. 4. is used, the operation issomewhat different. In this case the pins must be pushed in in theproper order, the pin N first, the

pin N second, and the pin N last, as other- The pin N is pushed infirst, and the teeth a on the cross-bar n push the springs-K of thewheels H and H from the said wheels, thus permitting the springs of thecorresponding wheels to turn the wheels in the direction of the arrow buntil their pins a rest on the pins I.

Then the pin N is pushed inward, which does not act on the spring K ofthe wheel H or H, but acts on the spring K of the wheel H thus againdisengaging the spring from the said wheel and permitting the spring Jto turn the .said wheel (if in aforward position) in the direction ofthe arrow 1) until the pin a of the said wheel H rests upon thecorresponding pin I. Then the pin N is pushed inward,

which does not acton any of the springs K.

If by mistake the pin N is pushed in first and the wheel H brought inits proper position, and then the pin N is pushed in, the teeth n actingon the springs K, release the same from the wheels H and H thuspermit-ting the springs J to swing the said wheels in the direction ofthe arrow 1), whereby the wheel H, which has been previously adjusted inthe proper position by pressing in the pin N twice, is again thrown outof its position,

and thus prevents the tumbler from being shifted in the direction of thearrow a and the with a frame or casing, a sliding bolt,'and a slidingtumbler, of a series of ratchet-wheels adapted to engage with thetumbler, a shaft on which said wheels are mounted, springs for turningthe several ratchet-wheels, locking-springs for locking theratchet-wheels in place, push-pins for turning the ratchetwheels, and apush-pin for disengaging the lockingsprings from the ratchet-wheels,substantially as herein shown and described.
